The Guru Index verdict
Mixed
~Mixed · 64%What the gurus are saying
Gurus agree hyaluronic acid is an effective hydrating ingredient, especially when paired with emollients, occlusives, and other humectants for sustained moisture. For dermal fillers specifically, the concern is longevity and placement: HA fillers last longer than FDA labeling suggests, and when injected shallow rather than deep on bone, they can migrate to the skin surface and cause swelling over time.
